Sam

Sam is an iguana that belongs to a guy who runs a meth lab in "Adventures in Hayleysitting". When he finds he doesn't get a receipt from Steve and his friends for cough medicine to make meth, he gets upset, leaving Sam to stare at the exacting expense records for the lab. When they track down Steve and his friends with Hayley, he holds them at gunpoint until they get the receipt from Jenny, a clerk that Steve wrote his phone number on the receipt for. As the meth dealer and Sam relax, they are shot and killed by Jenny's father.
